Definitions
- the invention relates to the field of power electronics. It starts from a converter circuit arrangement with a rectifier, in particular in 12-pulse Topology, and an inverter connected via an intermediate circuit according to the preamble of the first claim.
- a generic converter circuit arrangement comprises a rectifier, which in particular has a 12-pulse topology and a DC link feeds.
- the rectifier comprises a first partial rectifier, the on a star connection of an AC network is connected, and one second partial rectifier connected to a delta connection of the AC voltage network connected.
- a DC link can be connected to the partial rectifiers connected, e.g. feeds a downstream converter.
- the DC link an inverter is connected downstream, e.g. the shape of a three-point inverter can have.
- the components of this circuit arrangement must With regard to various failures on the rectifier, grid or inverter side to be protected.
- the intermediate circuit capacitors must not be overloaded.
- the rectifier In the event of a semiconductor failure the rectifier must suffer consequential damage be kept to a minimum. The same applies to the failure of one Inverter semiconductor.
- there should also be unusually high grid overvoltages can be intercepted without damage.
- the object of the invention is to provide a converter circuit arrangement which reliably against the above-mentioned rectifier, grid or inverter side Failures can be protected. This task is characterized by the characteristics of the independent claim solved.
- the essence of the invention is therefore that a protective circuit between the two partial rectifiers of the rectifier and an average potential of the DC link is switched.
- One embodiment is characterized in that the protective circuit voltage limiter elements, especially in the form of varistors or related Elements.
- the voltage limiter elements can also partially be switched on and off.
- Fig. 1 is a circuit diagram of the invention.
- Figure 1 shows a circuit diagram of an embodiment of the invention.
- a three-point inverter 9 is shown on the side of the figure Twelve-pulse rectifier 1, 2 via an intermediate circuit 4 with a plus 5, a minus 6 and a middle potential connection 8 is fed.
- the intermediate circuit 4 comprises in particular a capacitor bank C1, C2, and the inverter 9 protected from excessive current and voltage edges by a wiring network.
- the rectifier comprises two partial rectifiers 1 and 2, the first of which with a star connection of an AC network 3 and the second with a Delta connection of the AC voltage network is connected.
- the rectifier thus has the well-known 12-pulse topology.
- the inverter 9 also includes the semiconductor switches, e.g. GTOs, a circuit network with two current limiting chokes Ls1, Ls2, two resistors Rs1, Rs2, two wiring diodes Vcl1, Vcl2 and two wiring capacitors Ccl1, Cc12.
- the protection circuit comprises voltage limiter elements V1, V2, V3, in particular in the form of Varistors.
- the first voltage limiter element V1 is on the one hand with the first Partial rectifier 1 and a common node 7 connected.
- the second Voltage limiter element V2 is on the one hand with the second partial rectifier 2 and the common node 7 connected.
- the third voltage limiter element V3 is with the middle potential connection 8 and the common node 7 connected.
- the first and second voltage limiter elements 1 and 2 can be designed to be switchable on and off, e.g. a switch S1 or S2 parallel to it.
- the circuit works as follows:
- the required protective circuit is also simple and enables saving of numerous other wiring elements, especially the rectifier.

Abstract
Description
- Der Netzhauptschalter (nicht dargestellt) wird geschlossen. Die Schalter S1 und S2 bleiben offen bis die Zwischenkreisspannung Uzk stationär eingeschwungen ist. Sie ist deutlich kleiner als die Leerlaufspannung Uzk0, wenn die Spannungsbegrenzer V1 und V2 richtig ausgelegt werden.
- Der Schalter S1 wird geschlossen. Die Zwischenkreisspannung Uzkl erhöht sich, erreicht aber nicht die Leerlaufspannung Uzk10, da der Spannungsbegrenzer V3 eine begrenzende Wirkung hat.
- S1 wird geöffnet und S2 geschlossen. Die Zwischenkreisspannung Uzk2 erhöht sich, erreicht aber nicht die Leerlaufspannung Uzk20, da der Spannungsbegrenzer V3 eine begrenzende Wirkung hat.
- S1 wird wieder geschlossen. Die Zwischenkreisspannung überschwingt um den Betrag der Schwellspannung nur leicht, wenn V3 entsprechend ausgelegt wird.
